To all whom it may commu: n y

Be it knownthat I, FRANCIS F. JAMES, a

citizeny of the yUnited.States, residing at i y n l y y n lillustrating'the arrangement of the locking Washer. 'i

Philadelphia, in the county ofv Philadelphia and State of Pennsylvania,have-:invented new and useful Improvements in Shackle i Bolts,o-Whichthe following is a specifica tion. ff

The invention relates to a shackle b olt fof.' connecting va @springWith ythe shackle hangers. y y An object `of the present invention is toimprovethe construction of shacklek bolts f n K v i sleeve 3 with thecone 4. The bronze cone and to provide a simple, practical andeiiicientdevice of strong, durable and inexpensive construction adapted tobereadily. ap. pliedtogthe springs aiidkshackle hangers ofV automobilesandother` vehicles, andy capable of-iready adjustment to enable theshackle hangers to beproperly spaced for .preventingwearof thepartsandvcapable also of effectuallyulooking the parts to prevent the same4from working loose; f

lt is .also` an obj eet-of the invention toprovide a shackle boltvequipped ywith 1a central bronze bushingand opposite' cone memberscapable of 'ready adjustment to take upvthe- Wear and constructed so.that the-re.willbe no liability of' causing the ormat-ionlof shoulderson the cone members or in the cone bushing' which might limit Iorotherwise interfere with the adjustment of the Vparts to..

take ,upl the Wear.

`With theseand .other Iobjects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings and pointedout in the claims hereto appended, it being understood that variouschanges in the form, uses of proportion and minor detailsofconstruction, within the scope of the claims, may be resorted to withoutdeparting from the spirit or sacrificing any of the advantages of theinvention. l

In the drawings, in which like characters of reference designatecorresponding parts in the several views:

Figure 1 is a longitudinal View of a shackle bolt constructed inaccordance with this invention, the cone and cone sleeve being shown ineleva-tion.

Figure 2 is a similar view, the cone members and other parts being shownin section.

Figure 3 is a detailed view of" the cone having the threaded shank.

Figure 4 is asimilar' yiew oftl`1 e @one sleeve.

Figure 5. is a transverse sectional view vthe invention, the shackleVbolt comprises a bronze conebushing 1 ,and cone 'members consisting ofav cone sleeve v and a cone 4 y 3 and which Vadjustably "connects Itherv cone conesleeveftit -Within the'jcone bearings 6 and thesaidfconesleeve and cone 4 are provided with annular grooves 8 'and 9,10-

cated at theends yoit thefbronz'e bushing 2 and cooperatingl with theinterior annular groove Q7 tofacilitateftlie adjustment ofthe conemembers by eliminatingV all liability of the formation of, shouldersineither the Vcone bushing orthe cone' members fwhichvmight 'limite oral'ect the adjustment of thecone"` members 3 and4 to take up the wear of*the` shackle bolt. `lfflhis will' enable a` lperfect fit' j of theparts to` be maintained atj'all times and. ytheiehwill be .no liabilityof 'twisting lor I,lost motion of the, parts.' The cone bearing isdesigned-to fit Within the eye or opening of a vehicle spring and thecone members 3 and 4 are provided beyond the grooves 8 and 9 withsimilar outer exteriorly threaded portions 10 and 11 adapted to receivethe shackle hangers which cooperate With the vehicle spring. The outerthreaded portions 10 and 11 are spaced fromthe conical journaledportions of the cone members 3 and 4. by the said annular grooves 8 and9 and providedk with an integral threading stein' orshank 5 which screwsinto the cone sleeve ioo they are provided with longitudinal grooves 12and 13 adapted to receive lugs y)ai of locking Washers 15 which arearranged on the outer threaded portions of the cone members and whichare adapted to bebent over nuts 16 for securing the same againstretrograde rotation. The outer threaded portions may be flattened atopposite sides at 17 and 18 or they may be of uniform diameter through-1out their entire length and thel cone member 4 is provided in its outerend with a threaded socket 19 adapted to receive a `device will securetheA cone members in their relative adjustment. Any other suitablelocking means may however, be employed.

While the bolt 1s illustrated in the drawing as a shackle bolt, it mayof course, kbe employed for any other purpose, and the outer portions ofthe cone members may be made either with or without the exterior threads10 and 11 in order that the `v'bolt may be applied to one piece as wellas two pieces lshackles or members. The groove of the bushingfacilitates lubrication of the parts.

lVhat is claimed is:

1. A shackle bolt including a cone provided at the inner end with anintegral threaded shank and cone sleeve interiorly threaded and arrangedon the shank, said cone and cone sleeve being provided with exteriorannular grooves, means for securing the cone and cone sleeve in theirrelative adjustment and a cone bushing having opposite inwardly taperedbearing portions receiving the cone and conel sleeve, said bushinghaving its ends located at the said annular grooves and being providedwith an interior centrally arranged groove of greater diameter than theinner ends of its bearing portions, said grooves cooperating to permitfree adjustment of the cone sleeve, cone and bushing, by preventing theformation of shoulders.

2. A shackle bolt comprising a cone provided at the inner end with anintegral oil passage threaded shank, a cone sleeve interiorly threadedand arranged on the said shank, said cone and cone sleeve being providedat their outer ends with similar exteriorly threaded portions and havingexterior annular grooves at the inner ends of the said threadedportions, and a cone bushing having opposite cone bearings and arrangedon the said cone and cone sleeve and provided with a central interiorannular groove spacing the bearing portions of the cone sleeve andcooperating with the exterior annular grooves of the cone and conesleeve to prevent the formation `of shoulders and insure free adjustmentof the cone and cone sleeve in the cone bushing.

3. A shackle -bolt comprising a cone provided at the inner end with anintegral threaded shank, a cone sleeve interiorly threaded and arran edon the said shank, said cone and cone s eeve being provided at theirouter ends with similar exteriorly threaded -portions and havingexterior annular grooves at the inner ends of the said threadedportions, a cone bushing having opposite cone bearings and arranged onthe said cone andcone sleeve and provided with a central interiorannular groove spacing the bearing portions of the cone sleeve andcooperating with the exterior annular grooves of the cone and conesleeve to prevent the formation of shoulders and insure free adjustmentof the cone and cone sleeve in the conebu'shing, and means for having athreaded engagement with the cone sleeve and the cone for connecting thethreaded extensions of the same with the shackles whereby the shacklesare maintained in proper spaced relation throughout the ad- ]ustment ofthe shackle bolt and the latter prevented from lateral tilting.

In testimony whereof AI have hereunto set my hand.

FRANCIS F. JAMES.
